Abstract

There is disclosed a level shift circuit which has a differential input, for receiving input signals, and a differential output, for supplying output signals derived from the input signals. The level shift circuit further includes a control level setting input, and a feedback circuit for setting a common mode level of the output signals to a level set on the control level setting input. This allows the output common mode to be set accurately, independently of the input common mode.
